Can acupuncture help reduce breast size?

Not a chance: There is no plausible way for acupuncture to actually reduce breast size. If you breast size is a problem, talk with your ob/gyn about how this can be addressed. If it is a major problem, you might be a candidate for a breast reduction surgery.

Unlikely: Acupuncture can help symptoms mediated by your nervous system. Although it will not harm anything, it is unlikely to cause a change in breast size.
